'I'he safety water cradle boat, in accordance with this invention,Vincludes `a `hull l5 compris'- ing a plurality of transverse framelsections lli and a completely enclosed sheet metal casingl I1 mounted onsaid transverse frame sections and forming a plurality of separate aircompartments I8, i9, etc. Each of said transversev frame 'sec tions I6has a central core layerZ of wood, and sheet metal face layers 2lmounted Ontheside faces ofthe core layersl 20. The core layers areformedwith a plurality of perforationsl 22 or other passages. However,these perforations or passages are closed by the face-layers 2|.Fastening elements, such as rivets 23 connect the layers' 2li and 2ltogether as a unit. Y Each of the air compartments I8, I8,.etc., isprovided with an air valve 24 by which'l compressed air may be forcedinto said compartment. The compartments are hermetically sealed f sothat if one or more becomes punctured, the remaining lcompartments willstill function to hold the boat afloat. The traverse frame sections IEare provided with plates 25 mounted at the top corners thereof andprovided with projecting studs 26 which engage through the metal casingil. Suitable nuts-or other fastening elements 21, are engaged on theouter ends of thesestuds 26 tol assist in joining the transverse framesec'- ti'ons 'f5 v"and casing v'I'l togetherv (see particularly Fig-."6in thisrespect); w z 1,51 i, -'Inehull' li'sprovide'd withan ,open topcabin 28' provided witli'a vfloor-2 il anda seat back 3llffthe-,co-nvenince c" f fa'fr 1 foperatoif- 'of the boat'.

The construction .is such that thecrank 32 may be manuallyv turned for driving the propeller 36 top'ropel't'hel boat.

Means is also provided for steering the boat, and this means includes asteering bar 38 pivotally mounted at its center by a pintle 39 mountedon the cabinet oor 29. The steering bar 38 is provided with a, pair offoot rests 40 on opposite sides of the pintle 39 by which the bar 38 maybe pivoted in one direction or the other. Cables 4l connect with theends of the bar 38 and are guided over pulleys 42 and through passages43 in the side Walls of the cabin 28 (see Fig. 6). These cables 4Iextend to the rear of the boat and extend over additional guidingpulleys 44 and then connect with opposite sides of a rudder 45 which ispivotally mounted in a frame 46 mounted on the boat.

A plurality of arms 50 is mounted on the sides of the hull I and supportfloats 5I. There are two of these oats 5I, each extending along one ofthe sides of the hull. Each float 5I includes a hollow metal casing 52divided by a plurality of discs or partitions 53 into a-plurality ofseparate chambers. AEach of the chambers is provided with a bladder 54which has the usual air control valve 55 by which the bladder maybesupplied with compressed air. The rear ends 5I of the oats `are bentupwards, as clearly shown in Figs. 1 and 5.. The iront ends 5I of thefloats are also benil upwards. These front ends are provided with wedgeshaped members 55 which will assist in cutting the water when the boatmoves forwards. Each .of `these wedge shaped members 56 is formed from ahollow body which is open at its rear end 51. The upturned ends 5Iextend into the open rear ends 5l' and then up through top openings inthe top walls of the members 56. The discs 53 may also be connectedkbysuitable connecting rods 53' to reinforce the floats 5I.

Each arm 55 is made from a stationary section 58 andan'adjustable'section 59. Each'stationary section-58 is fixedly mountedon the hull I5 of the boat and lextends outwards. Each section 59 isfixedly mounted on a float 5I and extends inwards. The inner ends of thesections 59- are pivotally connected by hinge constructions 60 withslides 6I sldably mounted on the sections 58. A set screw 62 threadedlyengages through eachstationary section and is adapted to abut a movablesection for holding these parts in relative pivoted positions. Setscrews 63 engage through the slides 4(il and abut the edges of `theVstationary sections 58 to hold the slides 6 I .in relatively fixedpositions.

The set 'screws 63 may be loosened and then the :floats 5| may bemovedyinwards or outwards, so ,as toplace Vthem at selectedpositionsrelative tothe hull Ii5. Then the'rset'screws 63 are tightened. ,In theevent .that a relatively light person is using the boat, it-will befound that the hull I5 floats ata higher elevation. In this event thefloats 5l will hang downwards andrest on the water. Ihesetscrews maythenbe extended downwardssoasto hold the hinge sections 59 in their.downwardly extended positions. Thus the set screws 62 prevent looseflapping of the floats 5! and serve todirectly communicate the buoyancyofthe floats 5'I to the hull I5.

The operation of the device is as follows:

A passenger may sit on the floor 28 of the cabin 28 and operate thepropelling and steering mechanisms of the boat. 'I'he oat-s 5I extendlaterally of the hull of the boat and stabilize the boat to preventA itfrom easily tipping over. The floats 5I are of such design that theyfacilitate cutting the Water and so reducing the head on resistance ofthe boat.
